The TRSS-RJ45/8 type network lightning arrester is a lightning protection measure taken by Zhejiang tohr Electric Co., Ltd. to independently develop and manufacture the network system.
According to the characteristics of the network system, we choose the high quality and low capacitance gas discharge tube, TVS and other devices. It has the advantages of small insertion loss, quick response speed, accurate clamping, low output pressure and so on. The effect of electromagnetic interference is small, the transmission is not affected, and it can be used in peace at any time.

Working principle of product

In the process of equipment operation, if there is abnormal voltage, the network arrester will play a protective role. When the protected device is running under normal working voltage, the arrester will not work, and it will be regarded as a circuit for the ground. Once the high voltage is present and the insulation of the protected equipment is endangered, the lightning arrester acts immediately and leads the high voltage impact current to the earth, thus limiting the amplitude of the voltage and protecting the insulation of the electrical equipment. When the overvoltage is gone, the arrester is restored to its original state quickly, so that the system can supply electricity normally. The main function of the lightning arrester is to reduce the voltage value of the protected equipment through the action of parallel discharge gap or nonlinear resistance, and to reduce the voltage value of the protected equipment, so as to protect the power equipment.

Use of attention

1. the standard RJ45 interface can be conveniently connected to the front end of the protected device, and the grounding path should be as short as possible, and the length should not exceed 1.5 meters.

2. when installing, pay attention to cables coming in and out of surge protective devices, so as to avoid the two coupling of surge.

3. the protected equipment must have good grounding, and the grounding impedance is in accordance with the relevant national standards.

4. After correct installation, it can work steadily for a long time. If it is found that the transmission performance of the system is reduced or the signal is interrupted due to the cause of surge protection, it should be maintained or replaced in time.
